Serverless Framework: Request must be smaller than 69905067 bytes for the UpdateFunctionCode operation

Question

I am using package uploading zipped file like

frameworkVersion: "=1.27.3"

service: recipes

provider:
  name: aws
  endpointType: REGIONAL
  runtime: python3.6
  stage: dev
  region: eu-central-1
  memorySize: 512
  deploymentBucket:
    name: dfki-meta
  versionFunctions: false
  stackTags:
    Project: DFKIAPP
  # Allows updates to all resources except deleting/replacing EC2 instances
  stackPolicy:
    - Effect: Allow
      Principal: "*"
      Action: "Update:*"
      Resource: "*"
    - Effect: Deny
      Principal: "*"
      Action:
        - Update: Replace
        - Update: Delete
      Resource: "*"
      Condition:
        StringEquals:
          ResourceType:
            - AWS::EC2::Instance
  # Access to RDS and S3 Bucket
  iamRoleStatements:
    -  Effect: "Allow"
       Action: "s3:ListBucket"
       Resource: "*"


package:
  individually: true

functions:
#  get_recipes:
#    handler: handler.get_recipes
#    module: recipes_crud
#    package:
#      individually: true
#    timeout: 30
#    events:
#      - http:
#          path: recipes
#          method: get
#          request:
#            parameters:
#              querystring:
#                persona: true

  get_recommendation:
    handler: handler.get_recommendation
    module: recipes_ml
    package:
      artifact: zipped_dir.zip
    timeout: 30
    events:
      - http:
          path: recipes/{id}
          method: get
          request:
            parameters:
              paths:
                id: true
              querystring:
                schaerfe_def: true
                saettig_def: true
                erfahrung_def: true
                schaerfe_wunsch: true
                saettig_wunsch: true
                erfahrung_wunsch: true
                gericht_wunsch: true
                stimmung_wunsch: true

Can not understand this error, isn't 52.18 under 69905067 bytes ?

Answer 1

The package size should be lower than 50MB according to the docs https://docs.aws.amazon.com/lambda/latest/dg/limits.html

from this blog post

The 20 MB addition presumably is there there to account for request overhead involved with the AWS API (e.g. base64 encoding of the zip file data). So far the 50 MB limit holds true-ish. But, we’re not defeated yet.

Answer 2

This seems to be an issue only while uploading individual lambda function using serverless but if you don't give --function parameter and deploy full stack then it works fine!!!
